GSFC also operates the Hubble Space Telescope, the James Webb Space Telescope, and the Goddard Earth Observing System, which are some of the most important tools in modern astronomy.
Space Telescope
Space telescopes are astronomical telescopes placed into orbit around Earth or sent into deep space to observe the universe. They are not subject to the effects of Earth’s atmosphere, allowing them to capture much clearer and more detailed images than ground-based telescopes. Space telescopes also have a wider range of electromagnetic wavelengths they can observe, including infrared, ultraviolet, and X-rays.
Some notable space telescopes include the Hubble Space Telescope, the Spitzer Space Telescope, and the Chandra X-ray Observatory. These telescopes have revolutionized our understanding of the universe, providing insights into the birth and evolution of stars and galaxies, the nature of black holes, and the potential for life on other planets.
Space telescopes are typically much more expensive than ground-based telescopes, and their launches and operations require significant resources. However, the scientific discoveries they have enabled have been invaluable, expanding our knowledge of the cosmos and inspiring generations of astronomers.
Nancy Roman Coronagraph
The Nancy Roman Coronagraph (NRC) is a NASA space telescope mission concept designed to study exoplanets and circumstellar disks. Launched in 2025, it will be equipped with a large aperture (4-6 meters) and a coronagraph to block out the bright light of host stars, allowing for direct imaging and spectroscopic characterization of exoplanets. The NRC will enable the study of exoplanet atmospheres, compositions, and dynamics, furthering our understanding of planetary formation and evolution in a variety of environments.
Telescope
A telescope is an optical instrument designed to collect light from distant objects and make them appear closer. It consists of an objective lens or mirror at the front of the telescope and an eyepiece lens or mirror at the back. The objective lens gathers light from the object and focuses it on the eyepiece, which magnifies the image.
Telescopes are used for a variety of purposes, including astronomy, surveillance, and navigation. The first telescopes were invented in the early 17th century, and they have since been used to make many important discoveries about the universe. Today, telescopes are used by astronomers to study stars, planets, galaxies, and other celestial objects.
Nancy Grace Roman Space Telescope Coronagraph
The Nancy Grace Roman Space Telescope is a NASA space telescope scheduled to launch in the mid-2020s. It will be equipped with a coronagraph, which is an instrument that can block out the bright light from a star to reveal objects that are much fainter, such as exoplanets.
The Roman coronagraph will use a combination of optics and detectors to suppress the light from a star by a factor of billions. This will allow it to detect exoplanets that are 10 billion times fainter than their host stars, which is a significant improvement over existing coronagraphs.
The Roman coronagraph will be used to study a variety of topics, including the formation and evolution of exoplanets, the search for habitable planets, and the characterization of exoplanet atmospheres. It is expected to make major contributions to our understanding of the universe and our place in it.

NASA Goddard Space Flight Center Telescope
The NASA Goddard Space Flight Center in Greenbelt, Maryland, houses several telescopes used for a wide range of astronomical observations. These telescopes include:
- Hubble Space Telescope (HST): An optical and ultraviolet space telescope launched in 1990 and still in operation. HST has revolutionized astronomy by providing high-resolution images and data on the cosmos.
- James Webb Space Telescope (JWST): An infrared space telescope launched in 2021. JWST is expected to study the earliest galaxies, black holes, and other celestial objects that formed shortly after the Big Bang.
- Chandra X-ray Observatory (CXO): A space telescope that observes X-rays from celestial sources such as black holes, supernovas, and active galactic nuclei.
- Neil Gehrels Swift Observatory (Swift): A space telescope that rapidly detects and observes gamma-ray bursts and other transient events in the universe.
- Cosmic Background Explorer (COBE): A space telescope launched in 1989 that measured the cosmic microwave background radiation, the leftover radiation from the Big Bang. COBE’s findings were a major confirmation of the Big Bang theory.
Space Telescope Coronagraph
A space telescope coronagraph is a specialized instrument designed to block out the overwhelming light from a nearby star, allowing astronomers to study the faint objects orbiting it, such as planets, moons, and debris disks. It works by using a series of carefully aligned mirrors and masks to create an artificial eclipse, obscuring the star while allowing light from the surrounding region to pass through. This enables scientists to detect and analyze the faint signals emitted by objects that would otherwise be lost in the star’s glare. Space telescope coronagraphs are essential tools for studying exoplanets, searching for signs of life beyond Earth, and exploring the dynamics of stellar systems.
